Re: Particulate Emissions Test: Brooklyn, Maryland

Dear Mr. Apel:

Enclosed you will find four copies of our report on the particulate emissions test we conducted at your plant. Based on our test results, the average grain loading of the three test runs does pass both EP9 New Source Performance Standards and those set by the State of Maryland. Therefore, the plant is operating in compliance with State and Federal Standards.

You will want to sign the report covers and send two copies to:

Mr. Craig Holdefer Maryland Air Management D i of Environmental Affairs P.O. Box 13387 Baltimore, MD 21203

You will need to keep one copy of the report at the plant. We certainly have enjoyed. working with you. Please let us know if we can be of further assistance.

RAMCON PERSONNEL

On August 3 & 4, 1989, personnel from RAMCON Environmental Corporation

conducted a source emissions test for particulate emissions compliance at 1.14.

Construction's McCarter batch mix asphalt plant located in Brooklyn, Maryland.

RAMCON personnel conducting the test were Dave Armstrong, Team Leader, and

David Bailey. Bruce Shrader was responsible for the laboratory analysis including

taring the beakers and filters and recording final data in the laboratory record

books. Custody of the samples was limited to Mr. Armstrong and Mr. Shrader.

The purpose of the test was to determine if the rate of particulate emissions from

this plant's baghouse is below or equal to the allowable N.S.P.S. emissions limit set

by US EPA and the State of Maryland.

II. Im3EsuE

Table I summarizes the test results. The grain W i g limitation for EPA is .04

gr/dscf as speafied in 39 FR 9314, March 8,1974,60.92 Standards for Particulate

Matter (I), as amended. The allowable emissions for the State of Maryland are

the same as those set by EPA.

On the basis of these test resutts, the average grain loading of the three test

runs was below the .04 gr/DSCF allowable emissions limitation set by EPA

and the State of Maryland. Therefore, the plant is operating in compliance

with State and Federal Standards.

A Method Used: Method 5 source sampling was conducted in

accordance with requirements of the U.S. Environmental Protection Agency as

set forth in 39 FR 9314, March 8, 1974,60.93, as amended.

0. Problems Encountered: No problems were encountered that affected testing.

C. Sampling Site: The emissions test was conducted after a baghouse 0; a square stack measuring 60.0" x 60.0" with an equivalent diameter of 60.0". Five sampling ports were placed 80.0" down (1.3 diameters upstream) from the top of the stack and 147" up (2.5 dheters downstream) from the last flow disturbance. The ports were evenly spaced on 12.0' centers. The two outside ports are 6.0" @om the side walls of the stack. Twenty points were sampled, four through each port for three minutes each.

N. THE SOURCE

IV. TQjESMGlE

I.A. Construction Materials employs a McCarter batch mix asphalt plant which is

used to manufacture hot mix asphalt for road pavement. The process consists of

blending prescribed portions of cold feed materials (sand, gravel, screenings,

chips, etc.) uniformly and adding sufficient hot asphalt oil to bind the mixture

together. After the hot asphalt mix is manufactured at the plant, it is transported

to the location where it is to be applied. The hot asphalt mix is spread evenly over

the surface with a paver then compacted with a heavy roller to produce the final

product.

The following to a general description of the plant's manufacturing process: The

cold feed materials (aggregate) are dumped into four separate bins which in turn

feed a common continuous conveyor. The aggregate is dispensed from the bins

in accordance with the desired formulsrtion onto the cold feed system conveyor, to

an inclined weigh conveyor, then to a rotating drum for continuous mixing and

drying at approximately 300°F. The dried aggregate is pulled by a bucket elevator

to the top of a gradation control unit which separates and stores the aggregate by

size. The required amount of each aggregate is dispensed into a weigh-hopper

and from there into a pugmill where the hot liquid asphalt pavement is mixed

thoroughly with the aggregate. The hot asphalt mix is then d i i g e d from the

storage silo through a slide gate into waiting dump trucks which transports the

material to a final destination for spreading. The rated capacity of the plant will

vary with each aggregate mix and moisture content with a 5% surface moisture

removal.

The mixer uses a burner fired with natural gas to heat air to dry the aggregate.

The air is drawn into the system via an exhaust fan. After passing through the gas burner, the air passes through a baghouse. The baghouse is manufactured by

McCarter. The exhaust gas is drawn through the baghouse and discharged to the

atmosphere through the stack. The design pressure drop across the tube sheet

is 1 - 2 inches of water. The particulate matter, which is removed by the

baghouse, is reinjected into the pugmill.

V1. LABORATORY PROCEDURES & RESULTS

1. Field Preparation

A FILTERS: Fiberglass 4' sampling filters are prepared as follows:

FWm are removed from their box and numbered on the back side with a fett pen. The numbering system is continuous from job to job. The flters are placed in a desiccator to dry for at least 24 hours. Clean plastic petri dishes, also numbered, top and bottom, are placed in the desiccator with the filters. After desiccation, the filters are removed, one at a time, and weighed on the Sartorius anaiytical balance then placed in the correspondingly numbered petri dish. Weights are then recorded in the lab record books. Three fitters are used for ea& complete particulate source emissions test and there should be several extra filters included as spares.

8. SILICA GEL: Si i i i Gel used for the test is prepared as follows:

s ApptoximElltely 200 g of sika gel is placed in a wide mouth 'Mason' type jar and dried in an wen at 1?5*C for two hours. The open jars are'removed and placed in a desiccator until cod for two hours and then tightly sealed. The jars are then numbered and weighed on the triple beam balance to the dosest tenth of a gram. This weight is recorded for each sealed jar. The number of silica gel jars used is the same as the number of filters, Silica gel should be indicating type, 6-16 mesh.

11. Post - Testing tab ...

A FILTERS: The filters are returned to the lab in their sealed petri dishes In the lab, the di ies are opened and placed into a d-r for at least 24 hours. Then the filters are weighed continuously every six hours until a constant weight is achieved AU data is recorded on the laboratory forms that will be bound in the test report.

6. SILICA GEL The silica gel used in the stack test is returned to the appropriate mason jar and sealed for transport to the laboratory where it is reweighed to a constant weight on a triple beam balance to the nearest tenth of a gram.

C. PROBE RINSINGS: In all tests where a probe washout analysis is necessary, this is accomplished in accordance with procedures specified in 'EPA Refweme Method 5'. These samples are returned to the lab in sealed mason jars for analysis. The front half of the filter holder is washed in accordance with the same procedures and included with the probe wash. Reagent or ACS grade acetone is used as the solvent. The backhalf of the f i b r holder is wasbed with deionized water into the impinger catch for appropriate analysis.

D. IMPINGER CATCH: In some testing cases, the liquid collected in the impingers must be analyzed for solid content This invohres a similar procedure to the probe wash solids determination, except that the liquid is deionized water.

E ACETONE: A blank analysis of acetone is conducted from the one gallon gtass container used in the field preparation. This acetone was upd in the field for rinsing the probe, node, and top haif of the fiiter holder. A blank analysis is performed prior to testing on all new containers cif acetone received from the manufacturer to insure that the quality of the acetone used will be exceed the .001% residual purity siandard

*

SPECIAL N m

When sampling sources high in moisture content, (such as asphalt plants) the filter paper sometimes sticks to the filter Wer. When the filter, it may tk. In order to maintain control of any small pieces of film paper which may be easily lost, they are washed with acetone into the probe washing. This makes the filter weight light (so metimgs negative) and the probe wash comspondihgly heavier. this laboratory procedure is taught by EPA in the 'Quality Assurance for Source Emissions Workshop' at Research Triangle Park and is approved by €PA

The Sartorius ba&nce is accurate to 0.1 mg and has a maxl'mum capacity of 200 grams. The bafance predsion (standard devi&'on) is 0.05 rng. Before weighing an item, the balance should first be zeroed. This step should be taken before every series of weighiigs. To do this, the balance should have all weight adjustments at the "zerom position. The bearn arrest lever (on the lower left hand side towad the rear of the balance) is then slowly pressed downward to the full release position. The lighted vernier state on the front of the cabinet should align with the "zero' with the mark on the cabinet If it is not so aligned, the adjustment knob on the right hand side (near the rear of the cabinet) shouM be turned carefully until the marks align. Now return the bearn arrest to the horizontal arrest position. The balance is now "zeroed'.

To weigh an item, it is first placed on the pan. And the sliding doors are dosed to avoid air current disturbance. The weight adjustment knob on the tight hand side must be at "zero'. The beam arrest is then slowly turned upward. The lighted scale at the front of the cabinet win now indicate the weight of the item in grams. If the scale goes past the divided area, the itern then exceeds 100 g weight (W 3 1/2 ounces) and it is necessary to arrest the balance @earn arrest lever) and move the lever for f W g weight away from you. It is located on the left hand side of the cabinet near the front, and is the knob dosest to the side of the cabinet The balance will not weigh items greater than 200 grams in mass, and trying to do this might ham the balance. Remember, this is a delicate precision instrument

After the beam is arrested in either weight range, the procedure is the same. When the weight of the item in grams is found, "dial in' that amount with the two knobs on the!& hand side (near the 100 g lever) color coded yellow and green. As you dial the weight, the digits will appear on the front of the cabinet. When the ptoper amount is dialed, carefully move the anest lever down with a slow, steady turn of the wrist The l i i dial wiil appear, and the right hand side knob (front of cabinet) is turned to align the mark with the lower ofthe two l i i xale divisions W*ch the mark appears between. when these marks are aligned, the two lighted digits along with the two i n d ' i on the right hand window on the cabinet front are fmctbal weight in grams (the decimal would appear before the lighted digits) and the whole number of grams weight is the amount inm on the lefL

In general, be sure that the beam is in 'arrest" podtion before placing weight on Or m g weight off of the pan. Don't 'did in' weight unless the beam is arrested. The balance is sensitive to wen a hand on the table near the balance, so be careful and painWeng in every movement while weighing.
